Alphabet’s $500 Billion Wipeout: AI Spending Fears Trigger Tech Selloff
Alphabet Inc. lost more than $500 billion in market value over two days as investors reacted sharply to the company’s third-quarter results, which revealed slowing growth in key businesses and escalating costs tied to artificial intelligence infrastructure. The selloff, which also dragged down the broader tech sector, underscores growing unease about the massive capital expenditures required to compete in the AI race.
Despite Google Cloud surging 103%, investor concerns over AI spending remain high. The company reported a larger negative free cash flow than analysts had expected while maintaining its full-year capital expenditure guidance of between $195 billion and $205 billion. Ad sales from search and other channels—a business line that accounts for roughly half of overall revenue and is critical to financing the massive AI investments—also missed forecasts, growing at the slowest pace in five quarters. Investors are closely watching whether the company can maintain its advertising revenue as more users turn to AI-powered tools to find information. For years, Google executives have argued that AI chatbots and features won’t cut significantly into its search business, but the latest results have reignited doubts.
The quarter also saw a sharp reversal in other income, which came in at $63 billion but remained positive, a stark contrast to the gains seen a year earlier and the windfall in the second quarter that was mainly driven by SpaceX and an investment in a private company later identified as Anthropic PBC. Meanwhile, Amazon maintained its plan to spend around $220 billion on capital expenditure this year, with a large part of the investment going towards AI, highlighting the industry-wide arms race that is pressuring profitability.
As tech stocks plunge, the focus now shifts to whether Alphabet can balance its aggressive AI investments with sustainable growth in its core advertising business. The coming quarters will be critical in determining if the company can convince investors that its spending will ultimately pay off.
